Although Xu Yun had used external methods to control Wang Yue's injury not long ago, this was only a temporary measure.
Something to say. .
This is a high-efficiency but short-term effect achieved through the specific effects of allicin and the close-to-zero drug resistance of Wang Yue, an ancient man.
That is what the saying goes, 'hang one's life'.
At present, the first batch of garlic juice prepared by Xu Yun has been used up, so intravenous injection has become a top priority.
However, considering that the red sea urchin used to make needles is not a common ingredient - or a common medicinal ingredient in this era, you need to go to major pharmacies and markets in Bianjing City to find it. It is estimated that it will be difficult to find the real thing today.
Therefore, Xu Yun could only prepare part of the allicin solution first and continue to revive Wang Yue through external application.
After doing these things, while there was still time, he tinkered with the plating solution for the needle.
That is...
silver.
Actually.
Xu Yun's initial plan was to use aluminum to make the needle plating solution.
However, according to the normal historical timeline, aluminum would not be officially produced until 1827. Before that, aluminum metal was quite rare.
It's not that Xu Yun can't continue rubbing his hands, but the process of preparing metal aluminum is very troublesome, and the complexity is even more difficult than the microscope and the generator combined.
At present, Wang Yue's illness obviously cannot last that long, so Xu Yun finally decided to use silver to prepare the plating solution.
Anyway, the plating solution only needs to ensure that the upper part of the sea urchin spines are not broken by the elasticity of the skin.
Even if some silver does enter the human body through the breach, this dose will not pose any threat to the human body at all.
At most, some protein around the wound has deteriorated, causing the scab to appear darker.
The melting temperature of silver is 961 degrees, which is a temperature range that can be easily reached in ancient times. It is not difficult to prepare.
Therefore, Xu Yun did not show off his skills too much. He simply made a small stove similar to a coal kiln out of clay. He used pressurization to increase the melting efficiency and ensure that the silver nuggets could be melted into liquid as soon as possible.
As for the silver used in the plating solution...
Naturally, I drew it from Lao Su.
After preparing these.
Xu Yun handed over the scene to a servant and moved the house himself.
That's right.
move place.
Mentioned previously.
At present, Xu Yun has entered the guest list, completely broken away from the slave status, and has become a standard 'guest'.
Therefore, his residence was naturally changed from the south wing to the east wing. It was considered a promotion and salary increase in the ancient sense.
Compared with the simple south wing, the east wing is much better.
For example, the room Xu Yun was assigned to was about twenty meters away from the courtyard where Wang Yue was. It was a small courtyard with a single family.
Not to mention anything else, the courtyard alone covers an area of about thirty square meters.
There is a big willow tree planted in the middle of the courtyard, and the shade of the tree is extremely cool.
On the left side of the willow tree, there is a small pond measuring one foot square, in which a few fish are swimming leisurely.
To the right of the willow tree is a grape trellis, and under the trellis is a lounge chair - the kind of old man's chair that came later.
When the sun goes down, ask the servants to cut some pieces of fruit and make a pot of fragrant tea.
Leaning back on the chair leisurely and looking at the night scene, it was quite comfortable.
Other than that.
The decoration in this room is also much better than the one in the south wing.
For example, there are desks, inkstones, incense altars, and even various intricately carved patterns beside the bed.
All day today.
Xu Yun not only made a generator by hand, but also invented electrolysis, using the corrosiveness of hydrochloric acid to open the door to the microscopic world for Lao Su.
The physical strength is okay, but the energy consumption is really quite big.
In addition, after moving home, the time has come to Xu Shi, which is more than eight o'clock in future generations.
So after a simple dinner, Xu Yun lay on the bed and fell into a deep sleep.
It was still a silent night.
...........
Perhaps because of the change of bed, Xu Yun had a very solid sleep, and he woke up naturally the next day.
Yes, no one woke him up today.
"ha....."
Seven or eight o'clock in the morning.
Xu Yun, who woke up naturally, stretched out and put on his new clothes - this was the cloth clothes that Lao Su had sent to cut for him yesterday. It was still a low-key and common gray style, but the fabric was countless times better than the original Tsing Yi.
Xu Yun then walked to the sink next to the door and turned a switch similar to a faucet.
Less than a moment.
Crash--
A stream of cool well water gushes out from it, gradually filling the basin.
Xu Yun washed his face with the water, opened the door, and planned to go find Lao Su.
As a result, after taking a few steps, a timid voice came from my ears:
"Wang...Brother Wang..."
Xu Yun looked around and found another acquaintance standing outside his door:
"Hey, third brother?"
It is not difficult to tell from the title given by this little boy that Yongzhu probably told him something.
Then Xu Yun walked quickly to Zhang San and patted his somewhat gray shoulder without any scruples:
"Third brother, where have you been these days? I haven't even seen you."
Seeing that Xu Yun's attitude towards him was the same as before, Zhang San's expression gradually relaxed a little.
Of course, there is still some restraint, but it is not as outrageous as a sadly thick barrier:
"My sister's baby was one month old yesterday, and I went to help my brother-in-law's house organize some things...
Wang... Brother Wang, I heard that you made a fortune in front of the master and moved to Dongyuan all at once? "
Xu Yun nodded towards him and said yes.
Zhang San has a child's nature, and he has never seen what he did in the past two days.
So it's no surprise.
The words "seeking luck and making merit" in his words were probably the gossip he heard from other servants.
After all, he was a thief who had just been fished out of the water a few days ago, and the next day he became the lowest servant, looking like an ordinary unlucky guy.
The result was less than a week.
He suddenly became Lao Su's guest. The servants should even call him 'Prince Gongzi' according to the normal title.
Except for young people like Zhang San, most of the servants must have some lemons and a few strange words in their hearts.
Then Xu Yun smiled and said to Zhang San:
"It's just good luck. After all, the diners and servants all work for the master, don't they?"
"No, no, no, that's different."
Hearing Xu Yun's words, Zhang San shook his head seriously, clasped his fingers and said:
"Other than the old governor and Sister Yue Lian, the average servant's monthly salary is only four to six guan, which is almost the limit.
But the offerings made by the diners are different.
I've heard that diners start with at least ten guan of money, and some even have 20 or 30 guan.
It's the same work for one month, but the diners can do it for five months! "
Looking at this little boy who was talking about monthly money from the first time they met, Xu Yun smiled, rubbed his head, and joked:
"In that case, if you have the chance, how about I teach you a few tricks so that you can become a disciple?"
According to Xu Yun's thinking, he and Zhang San are quite destined. If there is a chance, it would be okay for him to teach him some methods that can "change his life."
What he didn't expect was that Zhang San quietly glanced at Xu Yun's lower body and shook his head quickly:
"No, no, it's fine for me to be a servant. By the way, go and have your morning meal. The master seems to have something to do with you..."
As he spoke, Zhang San’s expression became even weirder:
"It seems that I bought something you wanted. You can stab and shoot it..."
Xu Yun didn't notice Zhang San's expression at this time, and focused entirely on his words:
"Oh? Found the red sea urchin in one night? Isn't that too fast?"
Originally, according to Xu Yun's idea, red sea urchins were rare inland, and they would probably have to go to Dengzhou to find them.
Including the time spent on the road, the guarantee will be enough for about three days.
how to say......
Lao Su is indeed a man who once served as prime minister. Even though he has been retired for three years, some of his methods are still quite sharp.
He probably used some extraordinary connections to find the red sea urchin Xu Yun needed in a short time.
For the morning snack in the east wing, someone will go to the street to buy it in advance, so there is no need to share it with the servants.
So after filling his stomach, Xu Yun stopped by the yard where he was working on the generator yesterday.
I only see this moment.
The generator and electrolytic cell he made yesterday are being placed in a corner, and the simple high-temperature furnace he built is smelting silver water - the melting point of iron is 1536 degrees, which is nearly 600 degrees higher than silver, so there is no need to worry about iron. Pans will melt unexpectedly.
Lao Su was standing next to the generator, seeming to be studying something.
Perhaps because he was too involved, he didn't even notice that Xu Yun had entered the hospital.
Seeing this, Xu Yun made a silent gesture to Zhang San, walked to Lao Su alone, and said:
"Master, I kept you waiting for a long time. Are you...?"
Lao Su raised his head when he heard this and nodded slightly when he saw Xu Yun:
"Oh, Xiao Wang is here, I am studying the generator you made."
Seeing that Lao Su's expression was somewhat leisurely, Xu Yun knew that Wang Yue's condition was probably relatively stable, so he took the initiative to follow:
"Sir, what did you discover?"
"It's hard to find out. I just gained a little bit."
Old Su Chao waved his hand, touched the generator with his chin, and said:
"I have been observing this thing for a long time and discovered a few details. Come and hear if they are correct."
Xu Yun quickly made a listening gesture.
Lao Su pointed to the stator of the generator and said:
“First of all, this loop is connected from end to end to form a loop.
I once tried to remove the charcoal blocks and found that the generator could not run.
Therefore I judge.
For this thing to work, it must first be a connected and closed inner ring. "
After speaking, he paused and continued without paying attention to Xu Yun's expression:
“The second issue is direction.
You see here, the two magnetic poles are opposite each other.
If according to what you said, everything in the world can be divided into particles,
Then the particles between the magnetic poles must move laterally according to the force of attraction.
But the direction of the rotating object inside is very strange:
When it rotates, different positions are in contact with the 'particles' of the magnetic pole at every moment, as if they are rubbing...
Combined with your previous action of letting the donkey pull and suck the surge, I made a second judgment that I didn’t know was right or wrong...
That's what you call 'electric energy'. It's actually the power generated by donkeys grinding and grinding, and it's generated through the 'friction' of internal transfer objects..."
yard.
Looking at Lao Su who was talking eloquently in front of him.
Xu Yun seemed calm on the surface, but he couldn't help but feel turbulent inside.
Although there are many shortcomings in Lao Su's statement, in future generations of physics classes, he would probably be punished by standing in the back row.
But don't forget.
This is the year 1100 AD.
A feudal era where there was no understanding of electrical energy standards.
Lao Su can make this kind of judgment by observing the generator, which is so awesome!
Although there is still a long, long gap in understanding Lao Suli's true principle of magnetism and electricity.
But his words basically summarized the two key elements of magnetism generating electricity:
In a closed circuit, the angle between the direction of movement of the conductor and the direction of the magnetic field lines is not 0.
Beyond here.
Lao Su's last sentence even named the essence of magnetism and electricity:
Magnetoelectricity is the transfer of electricity, the conversion of kinetic energy into electrical energy, moving away from or close to electric charges.
The Coulomb force does work and induces an electric current in the conductor.
If Xu Yunlaiping evaluates it, Lao Su is simply...
monster!
That's right, monster!
Then he took a deep breath and said to Lao Su:
"Master, your analysis is very close to the truth about the generator, but the specific concept involves a thing called electric current. Should we first..."
Lao Su raised his eyelids and glanced at him, pondered for a while, and asked:
"Xiao Wang, do you know much about electric current?"
"Understand a little bit."
Old Su nodded slightly, remembered this matter in his heart, and then said:
"In that case, let's go and give Zheng Ru an intravenous injection first. Look in that box. Is it the stinging pot you want?"
Xu Yun took advantage of the situation and looked around.
It was discovered that what Lao Su was referring to was a wooden water tank about thirty centimeters high.
Then he walked to the water tank and found several red sea urchins sinking at the bottom of the tank.
As a doctor of biology and a lover of Japanese food, Xu Yun determined the species of these sea urchins the moment he saw them:
There is no doubt that it is the red sea urchin!
Once the variety is correct, the rest is simple:
I saw that he first removed the spines of one of the red sea urchins, cleaned and disinfected it with alcohol, and then smeared molten silver water on the body surface.
Then while the silver water is condensing, take out 120 mg of the allicin alcohol solution in advance, mix it with 1000 ml of physiological saline, and stir evenly.
that's all.
A bottle of simple allicin injection is ready.
Another quarter of an hour or so passed.
The silver plating solution has been condensed.
Xu Yun took out a silver syringe from Lao Su - this thing was a syringe barrel made by Lao Su according to the diagram he gave, and there was a small buckle-type switch at the interface.
Xu Yun turned on the switch and inserted the needle tip from above the tube body.
The tip of the needle is infiltrated by the plating solution and is made into an inverted cone with a thick top and a thin bottom.
Therefore, when the needle tip emerges from the lower end to about 90%, the remaining thick and impenetrable part is left in the tube body.
Xu Yun closed the buckle again and completely fixed the needle tip.
So far.
An ancient silver syringe is now produced.
After doing this, Xu Yun followed Lao Su into the house.
Wang Yue was still sleeping at this time, but it could be seen from his face and breathing rate that the Lord Zhonghou was out of danger.
Seeing Xu Yun and Lao Su entering, Wang Zhen, who was accompanying him at the bedside, quickly stood up and bowed his hands towards the two of them:
"Uncle, Xiao Wang, you are here."
Xu Yun returned the salute to him, then shook the needle in his hand and said:
"Sir Captain, the injection has been prepared. Can we start the injection now?"
Wang Zhen quickly gave up his position. His trust in Xu Yun had reached a very high bottom:
"Please."
Xu Yun stepped forward and gave Wang Yue a simple skin test.
Twenty minutes later.
There was no abnormality in the area where Wang Yue performed the skin test.
That means the skin test is negative and there is no allergy.
Seeing this, Xu Yun glanced at Lao Su and Wang Zhen:
"Zhonghou's body can accept intravenous injection. Is the villain going to start here?"
Lao Su nodded:
"let's start."
Xu Yun took a deep breath after hearing this, sucked up the medicinal solution with a syringe, and exhausted the air.
At the same time, a simple tourniquet was tied on Wang Yue, he picked up Wang Yue's left hand, found the vein, and applied a bolus injection.
Xu Yun injected the injection very slowly to prevent accidents to the maximum extent.
A few minutes later.
After the injection of allicin injection was completed, Xu Yun's expression did not relax at all.
He knew that now was the most dangerous time.
Although intravenous injection is a quick-acting method of antibiotics, it also comes with high risks.
For example, an infusion reaction may occur, or too many drug particles may cause local blockage and insufficient blood supply, which may further lead to tissue hypoxia, edema, phlebitis, etc...
The only advantage Wang Yue has is that he is an ancient soldier, his physical fitness is much higher than that of ordinary people, and he does not have the drug resistance of later generations.
A quarter of an hour passed, and everything was normal for Wang Yue.
Two quarters of an hour...
Half an hour...
An hour...
Two hours later.
Everything was normal with Wang Yue. Lao Su even checked his pulse personally and found that the pulse condition was becoming more and more stable.
It is clear.
Intravenous injection.....
It worked.
...........
